66693b1a77 topology: change include path
Add support for relative (based on the path from the parsed
configuration file) and absolute include path without
ALSA_CONFIG_DIR environment variable usage. The dependency
on the alsa-lib config tree may be added on demand.

ef3a96367e topology: pre-processor: Add support for conditional includes
Add a new keyword "IncludeByKey" that will be used to conditional
include configuration files based on the argument value supplied during
build time. For example:

IncludeByKey.DMIC_CH_COUNT {
	"[1-4]"	"include/platform/intel/dmic-generic.conf"
}

The above config will include the dmic-generic.conf file if the argument
value for DMIC_CH_COUNT is between 1 and 4.

da8f90c424 topology: Add option to pass pre-processor definitions
Add a -D switch to be able to pass pre-processor definitions that will
be used to expand arguments in the input config file. This will be
useful to generate multiple topology binaries from the same input config
file with different argument values.

For example: if we had a pipeline config as follows:

Object.Pipeline {
	volume-playback.1 {
		dynamic_pipeline $DYNAMIC_PIPELINE
	}
}

We can define the variable for DYNAMIC_PIPELINE as:

Define {
	DYNAMIC_PIPELINE 0
}

And when pre-processing the conf file pass "-D DYNAMIC_PIPELINE=1" to
override the default value for dynamic_pipeline attribute in the input
conf file.

a1c2275090 topology:pre-process-object: merge object config with parent object config
An object can be declared within a class definition as follows:

Class.Pipeline.volume-playback {
	Object.Widget.pga.0 {
		ramp_step_ms 250
	}
}

While instantiating the volume-pipeline class, the pga object
could be modified as follows:

Object.Pipeline.volume-playback.0 {
	Object.Widget.pga.0 {
		format "s24le"
	}
}

When building the pga.0 object in the class definition, merge
the attributes declared in the volume-playback.0 object to create
a new config as follows to make sure that all attributes are
set for the pga object.

	Object.Widget.pga.0 {
		ramp_step_ms 250
                format "s24le"
        }

48ebb1dc0c topology: pre-process-object: Add support for pre-process objects with no builder
Some objects just need tobe processed to add their attributes
to the private data section of their parent objects.
An example of this would be the pdm_config objects for
DMIC DAI's. Each pdm_config object's attributes need
to be added as separate arrays in the DAI object's
private data.

Modify the signature of tplg_add_object_data() to pass
the array_name parameter when multiple objects of the
same type in the same parent are processed.

88c6dd6cf4 topology: pre-process-object: add support for updating automatic attributes
Classes definitions in Topology2.0 can have attributes
qualified with the "automatic" constraint. Values for
these attributes will be calculated by the compiler.
This patch provides a generic method for defining automatic
attributes computation logic for different classes.

To update automatic attributes for a class, add an item
in object_build_map with auto_attr_updater defined, and then
add updating logic in the custom auto_attr_updater function.

1832f6f254 topology: pre-process-object: add support for prepocessing child objects
Add support for processing object instances embedded
within objects and classes. For example:
		Object.Control.mixer."0" {
			#Channel register and shift for Front Left/Right
			Object.Base.channel."fl" {
				shift	0
			}
			Object.Base.channel."fr" {
			}

			Object.Base.tlv."vtlv_m64s2" {
				Object.Base.scale."m64s2" {
					mute	1
				}
			}

			Object.Base.ops."ctl" {
				info 	"volsw"
				#256 binds the mixer control to volume get/put handlers
				get 	256
				put 	256
			}
		}

and pga class embeds the mixer objects as follows:
Class.Widget."pga" {
...
Object.Control {
		mixer."0" {...}
		mixer."1" {...}
}

The pre-processor starts with the top-pevel PGA widget object
and processes the mixer objects in the class definition.
This will recursively pre-processes its child objects to add the channels,
tlv and ops.

the parent object with the reference to the object.
For example, the following object instance:

	Object.Base.data."SOF_ABI" {
		bytes	"0x03,0x12,0x01"
	}

would update the SectionManifest as follows:
SectionManifest."sof_manifest" {
	data [
		"SOF_ABI"
	]
}

571d1fe871 topology: pre-process-object: add data section for attributes with token reference
Objects that have attributes with token_ref need
to have separate SectionData and SectionVendorTuples
for each unique token_ref based on the attribute_sets
in the object's attribute_set_list.

Add the tplg_pp_add_object_data()
function to add the data[] refs in the object and also
the respective SectionData and SectionVendorTuples.

For example for the pga object:

Object.Widget.pga."0" {
	pipeline_id 2
	format s24le
	type pga
	no_pm 1
	uuid    "7e:67:7e:b7:f4:5f:88:41:af:14:fb:a8:bd:bf:8"
	period_sink_count 2
	period_source_count 2
	ramp_step_ms 250
        ramp_step_type "linear"
	mixer.0 {
		....
	}
	mixer.0.name "2 Master Playback Volume"
}

The following sections will be added:
SectionWidget.'pga.2.0' {
	index 2
	type pga
	no_pm 1
	mixer [
		"2 Master Playback Volume"
	]
	bytes [
	]
	data [
		"pga.2.0.sof_tkn_comp.word"
		"pga.2.0.sof_tkn_comp.string"
		"pga.2.0.sof_tkn_comp.uuid"
		"pga.2.0.sof_tkn_volume.word"
	]
}

SectionData."pga.2.0.sof_tkn_comp.word" {
	tuples	"pga.2.0.sof_tkn_comp.word"
}

SectionData."pga.2.0.sof_tkn_comp.string" {
	tuples	"pga.2.0.sof_tkn_comp.string"
}

SectionData."pga.2.0.sof_tkn_comp.uuid" {
	tuples	"pga.2.0.sof_tkn_comp.uuid"
}

SectionData."pga.2.0.sof_tkn_volume.word" {
	tuples	"pga.2.0.sof_tkn_volume.word"
}

SectionVendorTuples."pga.2.0.sof_tkn_comp.word" {
	tokens	"sof_tkn_comp"
	tuples."word" {
		period_source_count	"2"
		period_sink_count	"2"
	}
}

SectionVendorTuples."pga.2.0.sof_tkn_comp.string" {
	tokens	"sof_tkn_comp"
	tuples."string" {
		format	"s24le"
	}
}

SectionVendorTuples."pga.2.0.sof_tkn_comp.uuid" {
	tokens	"sof_tkn_comp"
	tuples."uuid" {
		uuid	"7e:67:7e:b7:f4:5f:88:41:af:14:fb:a8:bd:bf:8"
	}
}

SectionVendorTuples."pga.2.0.sof_tkn_volume.word" {
	tokens	"sof_tkn_volume"
	tuples."word" {
		ramp_step_ms	"250"
		ramp_step_type	"0"
	}
}

Note that the ramp_step_type of "linear" is converted
to the tuple value 0.

d999c267d3 topology: pre-process-object: Add support for processing Manifest object
The pre-processor converts the Topology2.0 objects into
the relevant sections by looking for attributes defined
in the template config for the section and reading the
attribute values from the object instance config.

The structure struct build_function_map contains the
mapping of the build function to use for each object
based on the type and name for the class that the object
belongs to. The manifest object is the simplest with
no attributes. So, the build function simply creates
a new Section called SectionManifest which will be
populated with the data section in the following patches.

1ca07d8dbc topology: pre-process-object: construct object name from its constructor attributes
An object's name is derived from its constructor attribute
values separated by '.'. For example, the name for the
host widget objects is derived from its index and direction
attribute values as follows:
Object.Widget.host."playback" {
	index 2
}

The name for the host widget object would be host.2.playback.

Alternatively, if the object has a name attribute, the class
definition may skip the constructor attributes and the name attribute
value will be used instead.

b2e85be668 topology: pre-process-object: check attribute validity
Attributes can have constraints set for valid values, min
or max values. If the attribute value is set in an object,
the value must be validated against the set constraints.

An example for attribute constraint would be:
DefineAttribute."direction" {
		constraints {
			valid_values [
				"playback"
				"capture"
			]
			tuple_values [
				0
				1
			]
		}
}

where the tuple_values array would translate the valid_values of
playback as 0 and capture as 1.

the attribute value in the following order:
1. Value set in object instance
2. Default value set in the object's class definition
3. Inherited value from the parent object
4. Value set in the object instance embedded in the parent object
5. Value set in the object instance embedded in the parent class definition

Mandatory attributes must be found in one of the above, resulting
in an error if not found.

4d413567b0 topology: pre-process-object: Add support for pre-processing Objects
Add support for pre-processing object instances in the input
config. An object's attributes can be set in multiple places
such as, within the object instance, default values in the class
defnition, inherited from a parent object or explicitly set
in a parent object. Before converting the object config into
the relevant section in the existing syntax, all the attribute
values must be consolidated into one place so that it is easy
to verify if all mandatory attributes are set.
Also, the name of the object will be constructed from the
attributes defined in the attributes.constructor[] config
in the class definition and the unique attribute's value
must be set from the value passed in the object instance.

This patch create a temporary config for each object instance
and populates its unique attribute value. The rest of the steps
will be added in the following patches.

a82058e6ec topology: Add support for pre-processing Topology2.0 syntax
This patch adds support for pre-processing the Topology2.0.
The '-p' switch add pre-processing support during compilation
and the '-P' switch is for converting the Topology2.0
configuration file into the existing syntax.

Topology2.0 is a high level keyword extension on top of the existing ALSA
conf topology format designed to:

1) Simplify the ALSA conf topology definitions by providing high level
   "classes" so topology designers need to write less config for common
   object definitions.

2) Allow simple reuse of objects. Define once and reuse (like M4) with
   the ability to alter objects configuration attributes from defaults.

3) Allow data type and value verification. This is not done today and
   frequently crops up in FW bug reports.

Common Topology Classes
-----------------------

Topology today has some common classes that are often reused throughout
with slightly altered configurations. i.e. widgets (components),
pipelines, dais and controls.

Topology2.0 introduces the high level concept of reusable "class" like
definition for that can be used to create topology objects.

Common Topology Attributes
--------------------------
Topology defines a lot of attributes per object with different types
and constraints. Today there is no easy way to validate type or
constraints and this can lead to many hard to find problems in FW at
runtime.

A new keyword "DefineAttribute" has been added to define attribute
constraints such as min value, max value, enum_values etc. This
then allows alsatplg to validate each topology object attribute.

Topology Classes define the list of attributes that they use and
whether the attribute is mandatory, can be overridden by parent users
or is immutable. This also helps alsatplg emit the appropriate errors
for attribute misuse.

Class constructor attributes
----------------------------
Some attributes in the class definition are declared as constructor
attributes and these will be used to construct the name of the object.
For ex: for the host widget, the index and direction are constructor
attributes and the name for the widget is derived as follows:
host.1.playback or host.2.capture etc.

Attribute Inheritance:
----------------------
One of the key features of Topology2.0 is how the attribute values are
propagated from a parent object to a child object. For ex: a pipeline
object can pass down the pipeline_id attribute to all its widgets.
Inheritance is implicit when an object and its embedded child objects
have matching names for a attribute/argument. Attribute values
set explicitly in an object instance always has precedence over
the values inherited from the parent object.
